Abstract
Abstract A system automatically monitors playing and wagering of a game. A card deck reader automatically reads a symbol identifying a respective rank and suit of each card in a deck before a first cards is removed. A chip tray reader automatically images the contents of a chip tray for verifying that proper amounts have been paid out and collected. A table monitor automatically images the activity occurring at a gaming table. Periodic comparison of the images identifies wagering, as well as the appearance, removal and position of cards and other game objects on the gaming table. The system detects prohibited playing and wagering patterns, and determines the win/loss percentage of the players and the dealer, as well as a number of other statistically relevant measures. The measurements provide automated security and real-time accounting.
